DAISY M. BARTEAU, OF CORONADO, CALIFORNIA.

WAVE-MOTOR.

Application filed November 15, 1910. Serial No. 592,530.

Specification of Letters Patent.

Patented May 2, 1911.

To all whom it may concern:

Be it known that I, DAISY M. BARTEAU, a citizen of the United States of America, residing at Coronado, in the county of San Diego and State of California, have invented certain new and useful Improvements in Wave-Motors, of which the following is a specification.

This invention relates to wave motors and has for its object the provision of a device constructed in such manner as to convert the uneven and intermittent movement of a float actuated by the oceans waves into continuous rotary movement of a power shaft, in one direction.

The foregoing object is accomplished by means of a structure in which both the vertical. and sidewise movements of the float are utilized as will be hereinafter set forth.

Further objects and advantages of the invention will be set forth in the detailed description which now follows:

In the accompanying drawings, Figure 1 is a plan view of a wave motor constructed in accordance with the invention, Fig. 2 is a detail perspective view of the upper portion of a float showing a housing carried thereon, Fig. 3 is a sectional view upon line 05-00 of Fig. 1, looking in the direction of the arrow (1, Fig. 4- is a sectional view upon line waa of Fig. 1, looking in the direction of the arrow b, Fig. 5 is a detail view of a connection between a swinging arm and a chain hereinafter described, Fig. 6 is a detail perspective view of the connections between the arms of a power lever, hereinafter described, and the members actuated thereby, Fig. 7 is a detail view illustrating a sliding rod which acts toimpart the movement of the float to said power lever, Fig. 8 is a detail sectional View through one of the cross-arms carried by said sliding rod, Fig. 9 is a partial end elevation of the float showing said cross-arms and the housing on the float, Fig. 10 is a detail view of a latch for securing a swinging closure which normally closes one side of said housing, Fig. 11 is a detail view of i one of the guides employed in connection with a toothed segment hereinafter described, and Figs. 12, 13, 14, and 15 are detail'views of the pawl and ratchet connections hereinafter described, upon lines 44; 2 2; 3-3 and 11 of Fig. 1, respectively,

Referring to the drawings, the numeral 5 designates a pier supported upon posts or piles 6. Located adjacent this pier, is a float 7. Anchor posts 8, 9, and 10 are located at suitable distances from the float and anchor chains 11, 12, and 13 lead from these posts to the .tloat. Mounted upon the top of the float is a housing 14, open at each end and having one of its sides normally closed by a hinged closure 15. A latch 16 normally holds this closure shut.

A rod 17 is slidably disposed in the tubular portion 18 of a power lever and carries a head 19 which limits the outward movement of said rod, to prevent the possibility of said rod working out of said lever. Upon its outer end (see Figs. 2 and 9), the rod 1.7 carries a spider 20. Housings 21 upon the ends of the arms of this spider receive antifriction balls 22 adapted to contact with the sides of the housing 14 of the float.

The head 19 is preferably oval as also is the tubular portion of power lever 18 (see Fig. 16) to prevent the rod 17 from turning and to consequently hold said spider in the proper position for the balls 22 to contact with the top, bottom, or sides of the housing 14, as will be readily understood.

Preferably the open end of the housing 14 next to the pier is slightly larger than the outer end thereof. Arms 24 and 25 are rigid with and extend from the inner end of the tubular member 18. The arm 24 terminates in a vertical shaft 26 which is journaled in collars 27 of a yoke 28. This yoke is in turn horizontally pivoted at 29 in bearings 30. A rigid arm 31 extends upwardly from the yoke 28 and carries a toothed segment 32 which meshes with a pinion 33 upon the end of a shaft 34. The shaft 34 is supported in bearings 35, and pulleys 36, and 37 are loosely mounted thereon. Ratchet wheels 38 and 39 are fast upon this shaft, and pawls 40 and 41 carried by the pulleys 36 and 37 engage said ratchet wheels (see Figs. 12 and 14.

A straight belt 42 leads from the pulley 37 to a pulley 43 of a countershaft 44, while a cross belt 45 leads from the pulley 36 to a pulley 46 upon said countershaft. The

ment, and an in-shore swinging movement. j

countershaft is mounted in bearings 47 and carries a pulley 48. A belt 49 transmits movement from the countershaft 44 to a pulley upon a power shaft 51. This power shaft preferably carries a balance wheel 52 and is mounted in bearings 53. o

The operation of the device up to this point is as follows: The shore line is designat'ed at A. The incoming wave not only elevates the float, but tends to bodily wash it toward the shore, it being apparent from 9 that the chains possess sufficient slack to permit a limited movement of the float in any direction. It will therefore be apparent that two movements are imparted to i the power lever. An up and down move- The portion of the device heretofore described utilizes the vertical movement of the float. During any horizontal or in-shore swinging movement of the float, the vertical shaft 26 merely turns in its bearings in the collars 27 and imparts no movement to the yoke 28, but any vertical movement of the power lever rocks the yoke 28 upon its pivots 29 and imparts a swinging movement to the segment 32'. This in turn, imparts 'oscillatory movement to the pinion 33 and to the shaft 34. This oscillatory movement of the shaft by means of the connections described, imparts continuous rotary movement in one direction to the countershaft 44 and from said 'countershaft, to the power shaft 51. This part of the structure has been employed in wave motors prior to this time and is well known to those skilled in the art. It consequently requires no further description.

The structure for utilizing the in-shore swinging movement of the float will now be described. 7

The arm 25 of the power lever terminates in a horizontal shaft 54. r This shaft is journaled in a yoke and this yoke is in turn, mounted to swing 'upon vertical pivots 56 of a bearing 57. A rigid arm '58 extends from this yoke and swings bodily therewith. The outer end of this'a'r'm 58 passes through a sleeve 59 that is carried by a flexible member 60. This flexible member 60 forms part of a belt 61 that passes over a pair of idler pulleys 62 (see Fig.4) and also over a pulley 63 that is fast upon a shaft 64. Any vertical movement'of the float merely rocks the horizontal shaft 54 in its bearings in the yoke 55, but any horizontal in-shore or off-shore swinging movement 'of the float rocks the yoke 55 upon its pivots 56 and bodily swings the arm 58 to thereby impart a back and forth "movement to the 'belt'61, and through said belt 'im parts an oscillatory movement to the shaft 64. By means of pulleys 65, 66,

67, 68, ratchet wheels 69 fast upon the shaft 64, straight and cross belts 75 and 76 and "pawls carried by the pulleys 65, and 66, the oscillatory movement of the shaft 64 is' converted into continuous rotation of the countershaft 44, and consequently into continuous rotation of the power shaft 51.

It will of course be understood that when the float seeks to return to its original position, the parts are moved in the reverse direction from that in which they move when the float is rising and moving toward the shore.

Guide members 71, carried by a bearing standard 72, serve to maintain the segment 32 in proper alinement with the pinion 33. The reason for providing the hinge closure 15 is to permit the rod 17 and lever 18 to be swung around upon the pier and entirely disengage it from the float in case a storm arises.

From the foregoing description, it will be seen that simple and eflicient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construe tion set forth, but includes within its purview such changes as may be made within the scope of the appended claims.
